I am seeing event ID #8194 in several servers when I try to make an image using VSS. The image appears to complete successfully, however the error is logged in the Application Log

Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005. This is often caused by incorrect security settings in either the writer or requestor process.

From the Access Permissions dialog, add the "Network Service" account with
Local Access allowed.
Close all open dialogs.
Restart the computer.
